Ecology- The scientific study of interactions among organisms and between organisms and their environment, or surroundings.
Biosphere- Contains the combined portions of the planet in which all of life exists, including land, water, and air, or atmosphere.
Species- A group of organisms so similar to one another that they can breed and produce fertile offspring.
Populations- Groups of individuals that belong to the same species and live in the same area.
Communities- Assemblages of different populations that live together in a defined area.
Ecosystem- A collection of all the organisms that live in particular place, together wit their nonliving, or physical environment.
Biome- A group of ecosystems that have the same climate and similar dominant communities
Energy Flow
Sunlight is the main energy source for life on Earth
Some types of organisms rely on the energy stored in inorganic chemical compounds
Evaporation- Water changes from liquid to gas as it rises into the sky
Condensation occurs in clouds

The Greenhouse Effect- Carbon dioxide, methane, water vapor, and a few other atmospheric gases trap heat energy and maintain Earth's temperature range.
Effect of latitude on climate- As a result of difference in latitude and thus the angle of heating, Earth has three main climate zones, polar, temperature, and tropical.
Biotic= living or once was
Abiotic= nonliving or never was
Community Interactions, such as competition, predation and various forms of symbiosis, can powerfully affect an ecosystem
Competition- When organisms of the same or different species attempt to use an ecological resource in the same place
Predation- When one organism captures and feeds on another organism
Symbiosis- Any relationship in which two species live closely together
Mutualism- Both species benefit from the relationship
Commensalism- One member of the association benefits and the other is neither helped nor harmed
Parasitism- One organism lives on or inside another organism and harms it
Succession
Primary- Succession that occurs on surfaces where no soil exists
Secondary- When the disturbance is over, community interactions tend to restore the ecosystem to its original condition
